Concrete connection specimens subjected to positive-negative cyclic loading were experimentally investigated in order to research their shear transfer mechanism on the effect of different connection width. Parameters among specimens are varied in different connection width, dowel reinforcement diameter, compressive strength of joint mortar and friction along connection interface. Test results, including load-displacement curves, failure state, stress distribution along dowel reinforcement, indicated that concrete and dowel reinforcement reached their plastic ability at relative slip displacement 5 s=2mm, and shear force at slip displacement 2mm was conducted by dowel action of connection reinforcement and the capacity of joint mortar due to the friction force along connection interface. Formula of shear transfer capacity was proposed considering bearing pressure capacity and shear friction capacity using plastic dowel and compressive strut resistance mechanisms. The experimental data was compared with proposed shear transfer formula It was concluded that the formula gave a good prediction for experimental results.
